Senra's workflow preserves both a book's useful passages and the connections they trigger in his mind. He reads a physical book with a pen, six-inch ruler, Post-it notes, and scissors. When something stands out, he underlines it and writes the immediate association—often a parallel from another founder or business—on a Post-it attached to the page. He cuts notes to fit cleanly. After completing the book, he photographs the marked material into Readwise and checks that the text on screen matches the page. This laborious transfer creates a second or third exposure before the highlights enter a searchable database. He later rereads past highlights, allowing old material to inform new episodes and decisions.
Origin
Senra gives Ferriss a step-by-step account of the physical reading and Readwise process he uses to make Founders.
Core principles
- 01Attention is guided by intuition during the first read
- 02Associations matter alongside the author's literal words
- 03Manual transfer creates repeated exposure
- 04A searchable archive makes old highlights reusable
How to run it
- 1
Prepare the physical kit
Read with the book, a pen, a short ruler, Post-it notes, and scissors within reach.
Pro tip A ruler keeps underlining straight if visual order helps sustain attention.
Watch out The tools should support reading rather than become a reason to delay it.
- 2
Mark intuitive signals
Underline a passage whenever it stands out without forcing a complete analysis in the moment.
Pro tip Capture the essence that drew your attention.
Watch out Highlighting everything eliminates prioritization.
- 3
Record the association
Write whatever relevant comparison or idea came to mind on a Post-it and attach it to the page.
Pro tip Name the person, company, or decision that the passage resembles.
Watch out Keep the association distinguishable from the author's claim.
- 4
Transfer into Readwise
Photograph the marked passages and notes into a searchable highlight system after finishing the book.
Pro tip Use the transfer as another close reading rather than a clerical rush.
Watch out Optical character recognition can alter the source text.
- 5
Verify and revisit
Compare the digital capture with the page, then reread past highlights as part of the regular work cycle.
Pro tip Return to old highlights when preparing a related project or episode.
Watch out An archive that is never revisited becomes storage rather than synthesis.
In the wild
When Senra hears a friend discuss a large investment, his mind may connect it to how Fred Smith built FedEx, Jim Casey built UPS, or Buffett evaluated See's Candies. He writes that association beside the relevant passage.
→ The note preserves a cross-case connection rather than only the quoted sentence.
Common mistakes
Capturing text without associations
The workflow's distinctive value comes from preserving what the passage triggered, not merely reproducing it.
Trusting the digital transfer blindly
The photographed or OCR-generated text must be checked against the physical page.
Is it for you?
Best for
Deep readers who value physical books and are willing to trade speed for repeated contact with source material.
Not ideal for
People who need a fast, low-maintenance capture process or cannot alter their copy of a book.
From the transcript
“I sit down, uh, book, physical book, pen, 6-in ruler, post-it notes, and scissors.”
“if something jumps out to me, I highlight.”
“I have to take pictures of it into the Read Wise app”
